    • Test methods are provided for determining the amount of contaminants in a carbon black sample. The test procedures include screening a known amount of carbon black to separate larger particles in the sample from smaller particles. The sample and/or separated larger particles are treated with a separating force to disperse larger agglomerates of carbon black into smaller aggregates of carbon black and to separate contaminants from carbon black aggregates. The treated sample or separated larger particles can then be screened to again separate larger particles from smaller particles. The separating force may be a water wash stream which contacts the sample or separated larger particles at a pressure of from about 15 psi to about 35 psi. The separating force may instead or additionally be generated by a dispersing agent which can be combined with the sample or separated larger particles in an amount or concentration sufficient to disperse larger agglomerates of carbon black into smaller carbon black aggregates. The measured weight of the separated contaminants and the measured weight of the carbon black sample can be used to determine the weight percent of certain contaminants in the carbon black sample.
    • 提供测试方法来确定炭黑样品中污染物的量。 测试程序包括筛选已知量的炭黑以将样品中的较大颗粒与较小颗粒分离。 用分离力处理样品和/或分离的较大颗粒以将较大的炭黑附聚物分散成较小的炭黑聚集体,并将污染物与炭黑聚集体分离。 然后可以将经处理的样品或分离的较大颗粒进行筛选,以再次从较小颗粒分离更大的颗粒。 分离力可以是在约15psi至约35psi的压力下接触样品或分离的较大颗粒的水洗流。 分离力可以替代地或另外由分散剂产生,分散剂可以与样品或分离的较大的颗粒结合,其量或浓度足以将较大的炭黑附聚物分散到较小的炭黑聚集体中。 分离的污染物的测量重量和炭黑样品的测量重量可用于确定炭黑样品中某些污染物的重量百分数。

    • An improved rotary-type selector switch for fan speed control or the like including curved terminal members supported upon a base member around a central boss extending therefrom and having a conductive contactor for selectively interconnecting said terminal members when said contactor is pivoted. A cover member is attached to the contactor for pivotal movement together and retains springs which push the contactor against the terminal members and permit movement of the cover toward the contactor. The aforedescribed parts are assembled by a pin fastener with an expandable first end portion which engages the base in snapfitting relation and an enlarged second end portion overlying the cover member. Circumferentially spaced detent means and a projecting ridge formed between the pin fastener and the cover operably engage one another positively to locate the cover and connected contactor in a plurality of annular positions with respect to the base member.
    • 一种用于风扇速度控制的改进的旋转式选择开关等,包括支撑在从其延伸的中心凸台周围的基底构件上的弯曲端子构件,并且具有导电接触器,用于当所述接触器枢转时选择性地互连所述端子构件。 盖构件附接到接触器以枢转运动在一起并且保持弹簧,其将接触器推靠在端子构件上并允许盖朝向接触器移动。 上述部件由具有可卡合第一端部的可拉紧的第一端部和与盖部件重叠的扩大的第二端部组装在一起。 环形间隔开的制动装置和形成在销紧固件和盖之间的突出的凸起可操作地相互接合,以将盖和连接的接触器相对于基座构件定位在多个环形位置。
